1 Claim. (Cl. 131-207) 'I'his invention relates to a structurally andfunctionally improved mouthpiece to be used by a smoker. While it mightbe advantageously employed in numerous different associations, it isprimarily intended to serve as a mouthpiece for a pipe.

It is an object of the invention to provide a novel and improvedcartridge holder wherein the cartridge is always exposed to the currentsof the atmosphere during smoking to provide for a relatively cool smoke.Another object resides in the provision of a cartridge holder in theform of a hollow casing provided |with longitudinally spaced tubularanterior and posterior portions interconnected by circumferentiallyspaced relatively narrow ribs defining gaps leading to and incommunication with the internal chamber of the holder between theanterior and posterior tubular portions. Another object resides in theprovision of a nipple detachably associated with the holder and having arearwardly expanding tapered bore for 'wedgeably supporting the anteriorend of the cartridge. A further object is realized in the provision of aforwardly expanding tapered bore in the posterior tubular portion of theholder to frictionally sustain the posterior end of the cartridge.

With these and other objects in mind, reference is had to the attachedsheet of drawings illustrating one practical embodiment .of theinvention and in which:

Fig. l is a longitudinal sectional view of the pipe according to myinvention, showing the conventional bowl and the cartridge partly brokenaway;

Fig. 2 is an enlarged transverse sectional View on the line 2 2 of Fig.1;

Fig. 3 is a perspective view of the mouthpiece; and

Fig. 4 is an exploded view of the parts of the assembly as shown in Fig.1.

In the drawings, the pipe, generally denoted P, comprises the tobaccoreceiving bowl B land the laterally extending shank S having channelcommunicating with bore 11 of the bowl. It Iwill be observed that shankS also includes bore 12 in communication with channel 10. Bore 12retains the anterior tubular portion 13 of nipple N having annularflange 14 adapted to abut the rear end of shank S. Nipple N alsoincludes the posterior externally threaded hollow portion 15 adapted toengage the internally threaded annular front end or anterior portion 16of the cartridge mouthpiece or holder CH which includes a posteriorannular portion 17 provided with the forwardly expanding tapered opening18. Portion 17 is continued in the form of a bit 19 provided with a bore20. The 'width of this bit is-as 'shownsub stantially equal to thediameter of the holder, so that the latter may readily be manipulatedand continuity of appearance will be maintained.

The holder CH is a one piece hollow member or casing and although shownas of a suitable plastic may be of any other proper material. However,its anterior cylindrical and internally threaded portion 16 and itsposterior hollow portion 17 are appreciably spaced apart althoughpreferably integrally interconnected by circumferentially lice spacedribs R defining the spaced gaps 21, leading to and communicating withchamber or bore 40 intermediate the anterior and posterior hollowportions 16 and 17 of the holder.

The tubular filter cartridge FC is cylindrical and may consist ofseveral plies of moisture and nicotine absorbing and relatively thickpaper 22 and 23 defining an impervious outer layer and an internal bore24 interrupted Aby a web of diametrically arranged stitches carried bythe inner ply 23. These stitches may bev'of cotton or the like adaptedto filter the ow through the mouthpiece. As is .well understood, plies22 and 23 also absorb tars andv otherproducts of condensation in thesmoke.

With the cartridge holder CH disconnected from nipple N, the filtercartridge FC may be inserted throughthe annular or ring shaped front endor portion 16 into holder CH until the rear or posterior end 26 of thecartridge wedges slightly against the tapered surface defining bore 18.By this action the cartridge is not only frictionally held in holder CHbut is concentrically disposed therein across the internal chamber 40.In such relation the cartridge is spa/ced from the inner arcuate faces27 of ribs R and exposed to the atmosphere.

Holder CH is now moved towards nipple N whereby front or anterior end 28of the cartridge is received by the nipple N. More specifically at thistime, the holder is rotated and the internal threads 29 of the frontportion 16 coact 'with the external threads 30 of the hollow posteriorpart 15 of nipple N. Eventually head or front portion 16 meets theannular stop flange 14 and at this time the front end 28 of cartridge FChas been slightly compressed and has wedged itself against therearwardly expanding tapered bore or opening 31 of the anterior part 13of nipple N. Stated in another way, the front and rear ends of thecartridge are frictionally retained by nipple N and by the holder CH butin spaced relation in respect to ribs R, thus fully supporting thecartridge to maintain its concentric position across the holder. Also,the filter will have its adjacent end substantially sealed in engagementwith the surface 18.

During smoking, fumes reach bore 31, are conducted through bore 24 ofthe cartridge FC where the fumes are filtered after Iwhich the filteredfumes are conducted Ithrough bore 20 to the user. Thus, by the presentinvention the cartridge serves as the only passage for, conduct-ing thesmoke between nipple and the rear end of the holder, or stated inanother way for conducting the smoke longitudinally of chamber 40. Sincethe cartridge is always in view during and after smoking, it can berealized at once whether it needs replacement by a new filter afterhaving reached its' maximum efficiency. Even during smoking, thecartridge is always yopen or exposed to the atmosphere. Consequentlycurrents of air pass over the outside surface of the cartridge, thustending to provide a cool smoke.

As will be apparent, the present mouthpiece serves as a framework toproperly support the filter element. This framework may readilybemaintained in clean condition. When it is necessary to replace a filterand with the front end of the mouthpiece unobstructed, the user mayreadily insert the tips of his thumb and linger through the gapsexisting between the ribs to contact the outer face of the filterelement. Thereupon, the latter may be axially shifted to remove it fromassociation 'with the mouthpiece. By reversing this operation, a newlter element may be placed in operative association with the mouthpiece.

Various changes may be made in details of construction and arrangementof parts 'without departing from the scope of the invention orsacrificing any of the advantages inherent therein.
